If you are impatient I would recommend beta 3.8777. I am running it and I have no problems with scheduler. It also seems to include some fixes for xiaomi.
I don't have any installation package for it, but I have compiled it from source using a commit from 12. december.

is there a stable version with python allowed for windows ?
the last one and beta doesn't support python anyway
V3.8833 and V3.8153 have the same pb :

EventSystem - Python: Failed dynamic library load, install the latest libpython3.x library that is available for your platform.
even if python is already installed and PATH mofified to point on python, python/libs, python/scripts

If i use the guide and use
Get the source code and compile with:
git clone https://github.com/domoticz/domoticz.git domoticz
cd domoticz
git pull
cmake -DCMAKE_BUILD_TYPE=Release .
sudo apt-get install zlib1g-dev
make
it work but install last BETA release.

I tried ubuntu and debian.
In my Raspy all work great.
I do not know what to do
